The document describes the E-Ball, a conceptual spherical computer with a diameter of only 6 inches. It would contain all standard computer components like a motherboard, hard drive, RAM, speakers and wireless keyboard and mouse. Information would be projected onto surfaces using an internal LCD or DLP projector. The virtual keyboard would use infrared or laser detection to register key presses without physical keys. While innovative and portable, challenges include the need for specialized operating systems and high production costs.

3. INTRODUCTION
• The E-Ball is a sphere shaped computer concept which is the smallest design among all the laptops and
desktops have ever made.
• It’s not going to be like a PDA, it’s going to be a PC with all conventional components namely mouse,
keyboard, normal screen.

HICH CAN BE
USED IN E-BALL ARE
1. LCD projectors

11. CONTD…
•
Metal halide lamp is emitting the light.
•
Series of di-chroic filters are separates light.
•
3 polysillicon panels placed in red, blue, green color's
•
These primary color's are making the image.
•
Metal halide lamps are output an ideal color temperature.
•
LCD technology is used by many manufactures such as Epson, Hitachi,
and NEC.
11

12. ADVANTAGES OF LCD
•
•
LCD is generally more light efficient than DLP.
•
1000 lumen LCD is more preferred than 1200 lumen
DLP .
•
•
•
•
LCD trends to produce a sharper image.
3LCD projectors can project bright, vivid images with a
low output lamp.
More accurate color.
Sharper image
More light efficient.

13. DISADVANTAGES
•
•
•
•
•
•
•
More bulky as there are more internal components.
Dead Pixels.
LCD panel can fail
Screen door effect.
Contrast.
Portability.
Image degradation.

14. DLP PROJECTORS.
•
DLP-Digital Light Processing.
•
Worlds only all-digital display solution.
•
DLP technology is based on semiconductors called DMD chips.
•
Invented in 1987 by Texas.
•
DMD chips made up of many tiny mirrors.
•
Current DMD chip can produce 1024 shades of grey.
•
Found in projectors manufacturers of BenQ,InFocus and Optoma.

16. ADVANTAGES
•
Portability.
•
Higher contrast.
•
Reduced pixilation.
•
Reliability.
•
Sealed optics this makes it better for use in dusty
environment.
•
Less screen door effect.
16

17. DISADVANTAGES
• Rainbow effect.
• Light leakage.
• High cost.

18. LASER KEYBOARD
(VIRTUAL KEYBOARD)
• A Virtual Keyboard is a projection keyboard that is projected and
touched on any surface
• User operates by typing on or within a wireless or optical
-detectable surface or area rather than by depressing physical
keys.
• Proved nightmare for users
• Way to eliminate finger cramping
18

19. W
HAT ACTUALLY IT IS:• Keyboard that a user operates by typing (moving
fingers) on or within a wireless or optical-detectable
surface or area rather than by depressing physical
keys.
19

20. TECHNOLOGIES USED:•
•
In one technology, the keyboard is projected optically on
a flat surface and, as the user touches the image of a
key, the optical device detects the stroke and sends it to
the computer.
In another technology, the keyboard is projected on an
area and selected keys are transmitted as wireless
signals using the short-range Bluetooth technology.
•
With either approach, a virtual keyboard makes it
possible for the user of a very small smart phone or a
wearable computer to have full keyboard capability.
•
Theoretically, with either approach, the keyboard can be
in space and the user can type by moving fingers
through the air!
20

21. REASONS TO USE THE VIRTUAL
KEYBOARD.
• When connected to your handheld computer it is
more convenient to carry around than your laptop.
• It takes up less desk space than a conventional
keyboard.
• You could use it with your desktop, laptop or
handheld computer.
21

22. ADVANTAGES:•
Portability
•
Accuracy
•
Speed of text entry
•
Lack of need for flat or large typing surface
•
Ability to minimize the risk for repetitive strain injuries
•
Flexibility
•
Keyboard layouts can be changed by software allowing for foreign or Alternative keyboard
layouts.

23. IF THERE IS NO W
ALL?
• When we are working in an open place we can
make use of a paper sheet as a screen.
• paper sheet holder is placed at the back panel of
this computer.
• The holder can be opened by pressing it in the
lower part

26. THE SOFTW
ARE INTERFACE
The software interface of E-Ball concept pc is highly
stylized with icons that can be remembered easily that
support all type of windows operating system.
26

27. ADVANTAGES OF E-BALL:
• It is portable.
• E-Ball has large memory.
• Useful for making video presentations.
• These have greater speed.
• Supports
user-defined keyboard layouts
27

28. DISADVANTAGES OF E-BALL:
• Normal OS can’t work in these computers.
• Cost of E-Ball is very high.
• It is difficult to understand if any problems occur in
hardware components.
28

29. CONCLUSION
•
As years passes, the computer size is becoming
smaller.
•
Today’s technology is at its peak point beyond what we
could ever imagine.
•
New inventions and innovations are emerging on daily
basis.
•
Our imaginations have dressed into reality and today it
has become possible to have a whole computer in our
pocket all the time. This ball computer has taken the
